Application May 10, 1950, Serial No. 161,104

This invention relates to seeders and more particularly to a new andimproved seeder attachment for tractors whereby there is provided adurable light-weight seeder attachment that can be readily mounted onthe front of a tractor and to also provide a simple and eiiicient quickat-` tachable and detachable driving connection between a power take-offand the seeding mechanism.

The principal object of the present invention is to provide a new andimproved seeder for broadcasting brome grass seed, or the like, theuniform distribution of which is effective under forward movement of atractor.

The above and other objects will appear more fully from the followingmore detailed description, and from the drawing, wherein:

Fig. 1 is a front elevational view of the seeder showing the samesecured to the forward portion of a farm tractor.

Fig. 2 is a sectional view taken substantially on line 2--2 of Fig. 1.

Fig. 3 is an enlarged sectional view taken inside circle shown in Fig.2.

Fig. 4 is a sectional View taken substantially online 4--4 of Fig. 2;and

Fig. 5 is a view taken substantially on line 5-5 of Fig. 1. i

Referring now to the drawing, the numeral ID designates a well-knownfarm tractor. Secured to the tractor frame are a pair of channel ironmembers I I, the same being held rigidly in place by means of bolts I2,said channel members being opposed, as shown in Fig. 1, and the same areplaced to extend out beyond the radiator of the tractor, as shown bestin Fig. 2. Detachably secured to channels I I, by means of bolts I4, isa hopper I3, the same comprising a boxlike structure having a lid I5hinged as at I6, said hopper being approximately sixteen feet in lengthand having bracing members I1 spaced equi-distant, the entire length ofthe hopper. Superimposed upon the bottom of the hopper I3 is a plankmember I8, said plank being of lesser width than the bottom of thehopper, the same being tted into the hopper to form a trough I9,approximately two inches wide, said trough running the entire length ofthe hopper. Superimposed upon plank I8 is another floor member 20, saidoor member covering the entire bottom of said hopper and having thereina plurality of openings 2|, Fig. 5, opening into trough I9, the samebeing spaced apart and running the entire length of the hopper I3. Thebottom of the hopper contains a plurality of holes 22, the same 1 Claim.(Cl. 275-2) being bored near the back of the hopper into trough I9, butare so spaced that they are not in alignment with openings 2| in topfloor of hopper bottom. A chain 23 runs the entire length `of the hopperand nests within trough I9, the ends cf the chain extending throughopenings in` the ends of the hopper and are secured by means' of Cotterpins 25 to brackets 24, which in turn are secured to each end of a rodmember 26 which runs the entire length of the hopper on the outside backof same, being held thereon by means of brackets 2l, said brackets beingof means of bearing member 3l which in turn is supported upon a bracketmember 38 secured to guide wheel supporting members 39 by means of bolts46. The other end of flexible tube 35 is connected to a bearing box 4Iwhich is secured to bottom of hopper I3. A stud shaft 43 is mountedwithin said bearing box III and has rotatably mounted thereon a disc 44,said disc having formed radially therein a plurality of openings 45,adapted to receive a pin member 46 to secure one end of link member 29to disc 44.

The other end of link member 29 having a pin member 4'I by which it maybe quickly secured to stud 28 when it is desired to operate hoppermember I3.

The manner in which the device operates is as follows:

When the user wishes to seed a eld he rst makes sure that the link Z9 isdisconnected from stud 28, by removing pin 4l, so that rod member 26will not be oscillated when the tractor is in motion, i. e., until thetractor reaches the iield to be seeded, which is usually some distancefrom where a tractor is stored. Hopper I3 is first lled with the desiredtype of seed to be used, and this is usually done near the barn wherethe seed is stored. If it is necessary to pass through a farm gate inorder to reach the eld to be seeded, with the large sixteen foot hopperattached to the tractor in its normal seeding position, the user hassimply to remove one bolt.

3 such as either of bolts I4, Fig. 1, which allows the hopper I3 to beswung to a diagonal position in relation to the tractor and the entiretractor and hopper may then'be passed through an ordinary farm gatewithout trouble. When the field to be seeded is reached, the user simplyreturns hopper I3 to its normal seeding position, as shown in Fig. 1,and returns bolt It to hold it in place upon the. channelA memberssupplied` therefor. Link 29 is then secured to stud28, by means ofj pin41, Fig. 5, and the tractor started forward. As the tractor movesforward and guide Wheels; 33 rotate upon axle 32 to which disc 3l! issecured, disc 30 rotates in a contra-clockwise direction;- Inasmuch asspurgear 34 is so located thatthe` teeth thereof mesh with the openings3I in disc 30, spur gear 34 is also rotated inaclckwise''di rection, andthis movement is imparted, by means. of flexible tube 35, to which oneend of spur gear 34 is secured, to gear box il and to disc itaiclckwisel direction; One end of link 29 is se= cured, by means of pin`todisc rl4'^through` onefofthe openings liftherein, and thel otherend?r of;y link 2S`-is secured to stud Aon rod* member 26.1 A's--discI4-rotates link member 29causesrodv member 26; to oscillate, which invturn moves: chai1r23, each end ofwhich; is secured to arr endof rodmemberZS: The distance rod member-'2lt o scillatesis;controlledyby'the1opening to whichonerend of-linkl 29. is secured todisc 44.

Therahas been disclosedherein a` simple, yet4 unique mechanism, wherebya farmer may quickly 4 convert his tractor to a seeder by afew simplechanges. The large hopper may be quickly detached from its carryingchannel members and the Vtractor used for many purposes without in anyway disturbing the hopper driving mechamsm.

While I have described and illustrated a satisfactory device that hasproven highly successful in practical -operation, it will be understoodthat the invention is not limited to specific constructional detailsshown and described, but that many changes, variations and modificationsmay be resorted to without departing from the principles of myinvention.
